Geopsy: Subtract Signals

Subtract Signals pop-up window

Subtract Signals, reached from the Waveform menu, subtracts a signal or a group of signals from the signals in the active signal viewer. By clicking on Subtract Signals, a pop-up window appears with the following option:

• Subtract All signals in group. It allows to subtract from the signal in the active viewer a whole group selected in the box below listing the current groups. Clicking on the expanding sign ('+' under Windows, right arrow for Mac) displays the list of existing groups. Groups with a different number of signals compared to the active viewer are displayed in grey and/or cannot be selected. Signals in the active viewer are subtracted one by one with the signals in the group in its defined order (see Groups).
• Subtract A single signal. It allows to specify a signal in the combo box listing the signals in the active viewer only.

Subtract Signals modifies the temporary signals in the active viewer.
